[Equest-users] Matching Zone OA Flow Rates

[Scott Janssen]

My question  is in regards to matching the zone level OA flows between
the design and baseline models.  This particular project uses system
type 7 in the baseline model.  Generally, I get both models to roughly
where I want them to be, and then take the zone level OA flows from the
design model SV-A reports and copy them into the baseline model.  But
for some reason, this baseline model inflates any value I specify as the
zone level OA flow.  I've never had this issue before and I even tried
specifying much larger OA flows (i.e. 4,000 cfm instead of 500 cfm), but
when I check the SV-A reports for the baseline, the OA flow values
listed are always higher than I specified.  I've changed a number of
parameters, but I can't determine what's overruling my OA flow input.
The main air handlers in the models are 100% OA, but I've had 100% OA
AHUs in other projects and never had this issue.

 

Anyone have any suggestions?

 

Thanks in advance,

 

Scott
